I would like to fit a towbar to my 2005 VW Touran and would appreciate advice or tales of experience with regard to whether I need dedicated wiring or can make do with universal. We only want to fit a platform-style bike carrier (still tent campers!) so not towing as such. The car has a stabilisation programme for normal driving but not a trailer one.
I'm really not keen on the VW system as it will add at least £150 to the cost, £200 if they code the computer as well. Vehicle is not in warranty. Am just scared of messing up the entire electrics system.
If you look on Witter website you will see there is £115 diffence in price for universal single electric loom & dedicated single loom for your car. For a car age & type as yours, certainly universal electrics can be, & are fitted but the plug in dedicated type is imho, always going to be preferred.
As car is out of warranty the choice can be your own. I would have thought with single electrics, the universal kit would do the job.
In anycase I would use a fitting service who have a good reputation locally & are prepared to warranty their work.
The primary benefit of 'dedicated wiring' is that it will carry your ABS signal through to your van. So, only really useful if your van is fitted with a stability control requireing an ABS signal.
PS
With 'universal' electrics, a so called 'bypass relay' is used so that the 'CAN Bus' system on your car is uneffected.
Whether you go for 'universal' or 'dedicated', every modern car has a 'manual' produced by the car manufacturer that tells the towbar electrician EXACTLY how and where to connect the electrics. Just make sure they have the manual and are willing to do fitting in accordance with it. Don't be fobbed off on this point.
Thank you for your replies they are very helpful. johnjory - good tip regarding the car's manual - I would otherwise have forgotten to take that along!
Interestingly, of the two NTTA members in our area that I have spoken to, one was only prepared to fit a VW system (with many cautionary tales about £1000s pounds worth of damage to car electric systems), and the other seemed totally fine with a bypass route. Really, I think if we have to go the dedicated route, combined cost of towbar, fitting and decent cycle carrier is past a tipping point at which we all have to take up a cheaper hobby.
You are welcome, but you slightly misunderstood. Not your cars manual, but a specialist manual about the fitment of towbars to each model which the fitting company should have.
If a company is that cautionary, it suggests to me that they do not want to do the job. In reality, whilst it is quite skilled, it has also been totally systemised by the car manufacturer.
On a slightly different tak..If all you want to do is carry bikes, & I'm sure you don't want the cheapo strap on type, google for Fiamma website. As well as campervan bike racks they also do clamp on top & bottom bike rack to fit tailgates of cars such as yours. Probabley under £200 so less than a towbar.
